As you see in the crash report, the adobe frameworks crashed when drawing a view.

In that case you may have an old PDF plugin from Adobe installed. You could of course update the PDF Plugin.
Or you can check /Library/Internet Plug-Ins or ~/Library/Internet Plug-Ins folders for plugins. Those folders should normally be empty except Default Browser.plugin file.

If you remove the PDF plugin from Adobe, the webviewer will use the default plugin from WebKit, which may not crash. Try it!
